Application filed July a, 1908, ser'mi'm. 442,535. renewed September 10, 1900. Serial a... 518,072.

To all whom it may Be it known that I, \VILLIAM A. HUTTON, a citizen of the United States, residing at Scranton. in the county of Lackawanna and State of Pennsylvania, have invented certain new.and useful[Improvements inElectrio-Light Fixtures, of which the following is a-specilication. a

The purpose of my invention is to provide a separable supporting fixture for electric lightchandeliers or brackets so that the removed.

. in the accompanying drawings, Figure 1 is a side elevation of the fixture with a part of the tube or stem of a chandelier connected tl'iere'wi-th; Fig. 2 is a top plan view of the same; Fig. 3 is a section onthe line 33 of Fig. 2; Fig. 4 is a top plan view o'fthestationary member of the fixture; and, Figs. 5' and 6 are, respectively, a topplan view and a side view of. the collar which forms onemember of the fixture.

Referring to the drawings, A indicates the supporting member of the fixture, made in the form of a spider, having a central hub or body portion 1 and three equidistant arms 2, 3 and lwhich extend outwardly and upwardly from the body portion and are pro vided. with perforations through which fasteningd'evices, such as screws, may be in .scrlcd to secure the member to a. ceiling or wall. The hub portion has a central opening (3, and ribs or shoulders 7, 8 and 9 project inwardly from the interior wall of the hub. These shoulders are arranged at equal distances apart. leaving recesses or spaces 10, 1]. and 1.2, between the shoulders, nearl equal in width to the width of the siren dcrs. V-shaped dc n'cssions 13 are formed in the up per sides 0 the shoulders.

A tubular stem ll, which carries the electrio lights, and through which the conducting wires extend, has itsend portion 14 threaded and upon said end portion is arranged a clamping nut '15. A collar C is also arranged upon theend of. the stem; This collar may be p'ernninently secured to the stern, although, as shown in the draw ing, it is threaded on to the stem, and that has three laterally projecting arms 16 slightly narrower than the recesses 10 in the member A and the lower port-ions 16 of the arms are y ;shaped, as shown, so that they will fit into the V-shaped depressions 13. in the member A. a r v In the use of the invention the member A is permanently secured to the ceilin or to shoulders of the stationary member, and

after these arms have passed be and the shoulders, the stem 'is turned to ring the arms over the V-shaped depressionsin the shoulders. Owing to the V or wedge-shape of'the arms and depressions it is unnecessaryfor the operator to turn the stem until the arms on the collars are in exactpositions over the depressions, which would be diflicult, since both are out of view. When the stem is turned sufiiciently to bring the V- shaped arms over any part of the depressions in the shoulders, the stem maybe lowered and the arms, engaging the sides of the depressions, will adjust the nut and automaticall' find their seatsin the depressions. .When t e arms are seated, and the stem thereby supported, the latter may be turned relatively to the collar to adjust the lights, carried by the stem,'to the'desired position. The clamping nut is then tightened and the several parts of the fixture are thus held securely together/ To remove the stem from its position the clamping nut is loosened and the stem pushed inward slightly to raise the arms on the collar out of the depressions 9,5

inthe shoulders. 'l he'stom is then turned to bring the arms on the collars in line with the recesscsbetwecn' the shoulders and the stem is then pulled outward to separate the parts.

1. An electric light fixture comprising a supporting member having a central opening and having a plurality of inwardlyprojccting shoulders or supports, spaced apart.

from one another, said. shoulders having de- 105 ressionson their upper sides, a stem, a colar threaded on said stem, said collar having radially extending arms adapted to fit into said depressions and also adapted to pass through the spaces between said shoulders 1 10 mg and having a jecting shoulders and a clamping nution said stem adapted to e'nga e the lower side of the supporting 2. An electzic'light fixture comprising a' supporting member having a central openplurality of inwardly proor sup rts spaced apart from one another, said oulders having V-" shaped de ressions on their upper sides,'a stem, a co ar on said stem, said collar haved to into said V-shaped deplressions and I also adapted to tween said shou on said stem adapted to e 'side of the supporting mem er.
